Unit Load Calculation

7. Try to exchange modules between carriers to reduce the unit loads to 75 (if a
391C1 or 391A3 power supply is installed) or 54 (if a 391A1 or 391A2 power
supply is installed). (Remember that the 100D, 800 NI-BRI, 400 LS, 400 GS/LS,
800, and 800 GS/LS modules have unit loads of 0.0.) Repeat Steps 1 through 6
to recalculate unit loads for the new configuration.
NOTES:
Empty slots are not permitted between modules.
■ If the exchange reduces the unit load to below the rated maximum for your
power supply module, no further calculation is required.
■ If your system has a 391A1 or 391A2 power supply and the exchange does
not reduce the unit load to 54, replace the 391A1 or 391A2 power supply
with a 391C1 power supply. If your system has a 391C1 or 391A3 power
supply and the exchange does not reduce the unit load to 75, continue to
Step 8.
8. Calculate the unit load for slots 5 and 6 of the carrier using the table on the
next page.
■ If the unit load for slots 5 and 6 is less than or equal to 27, power is
sufficient for the carrier.
■ If the unit load for slots 5 and 6 is more than 27, continue to Step 9.
